How does the PowerBox work?

The CRD PowerBox works by modifying the electronic signals that control fuel pressure produced by the pump in order to optimize engine performance. The PowerBox senses and responds to changes in engine load/speed throughout the range of acceleration. With the PowerBox CRD, pressure accumulates faster in the rail and is readily maintained to deliver more power and torque. The result is smooth and responsive acceleration that produce sportier handling. The increased torque produced by the PowerBox enables the engine to operate more efficiently, so fuel consumption is minimized.
The PowerBox CRD will not override the safe operating parameters of your engine and does not change or interfere with ECU functioning.


The PowerBox CRD includes an extended wiring harness to provide greater reach for installation. The unit is equipped with plugs that are compatible with those in your vehicle. With the instructions provided, an inexperienced driver can complete the installation in just a few minutes (depending on make and model). Installation instructions are included.

Signal Variation Switch

The CRD PowerBox has a signal variation switch with 16 positions. Using a small screw driver, higher output can be achieved by turning the HEX switch to a higher setting.
